To think that my cleaner should be charging me less for not doing my floors?

[HalfWomanHalfFish]

I hire a cleaner once a fortnight.

You know we can read your edit right @HalfWomanHalfFish?

If she's still doing the full time without doing those things obvs you still pay in full. If it's a deal-breaker that those things aren't done then you need to find a new cleaner.

Probably pain I would think. Begs the question whether she should actually be a cleaner if there are expected standard housework tasks she can’t do - depends on customer expectations too I suppose.

I think when you get a cleaner, you decide between you both what you want done each week, then she will tell you how long it will take , then you both know what is expected to be done. Also the remember if the house is tidy then she can get straight on with the cleaning, and not be picking up stuff and putting things away. A cleaner is there to clean not tidy.

Agree with PPs - you probably need to find a new cleaner

If she is actually spending two hours cleaning, then you should pay her in full. If I were you, I would give her a month to recover, as accidents can happen. If it takes her longer than that to recover, I might ask her either to bring someone to help her or consider finding another cleaner.

From what you edited your opening post to - which is what most people will be replying to - then it is impossible to say. As pps have replied, it depends on what else you want completing and what you are happy to have left out.
Obviously, a chat with any cleaner about what can be done in the time, is needed.

Of course, if you'd posted your original post, with the information about your cleaner having issues with her hip and feeling she isn't able to clean your floors, you might have got different responses...... possibly along the lines of how is it she can vacuum but not mop.... or possibly along the lines of how long she has worked for you and is that loyalty and other good service something you'd want to take into consideration with some reasonable adjustment to the contract or agreement you have with her.
